To all fui/wm t may concern: l

Be it known that I. HANS Z. NnLsoN, a

citizen oit the United States, and a resident oit Albert Lea, in the county yof Freeborn tain new and usefulv lnmrovements in Vaporizing and Superh'eatmg l Incandescent cation.

This invention relates to devices Wh ich are provided with gasolene and air supply pipes, mantles and vaporizcrs, andwith which devices gasolene is vaporized, said vapor mixed with a suitable quantity of air andv burned ivithin the mantle, and thereby said mantle is heated to incandescence; and the yvaporization of gasolene is thereafter rating or vaporizing tube which` is .located Within the heat zone ol the mantle. And the` principal. objects ot this invention are to obtain a device ot' the charac-.ter de' scribed which is provided with a removable saperheater so situated that'gasolene vapor is discharged thereinto from the vaporizei: or generator' ofthe device whereby said vapor While flowing through the superheaterto the vapor nozzle in a highly heated condition.

'A further object is to obtain a' Bunsen discharged from the nozzle and air 'at a much lower temperature than Isaid vapor, andV saidllunsen tube ,discharging intoV a mixing a'nd expanding chamber, Where said air will beheated and expanded and thoroughly mixed with the vapor; the discharge. end of said mixing and expanding chamber combined air and vapor passage Way having a. burner at the lower end thereof, said burner provided with an inverted mantle thereover.

A further object of the invention is to so dispose the several parts of the device that the air inlet, the Bunscn tube, the mixing and expanding chamber, the needle valve, and the vapor generating passage Way of.` the. device will all be contained in aV single A further object of the invention .is to casting so that. the screw threads necessarily' required need to be cut with reasonable closeness only, and no gasolenc or gasolne vapor Vcan escape therethrough.

A 'further object is to so construct. thesuperheatig element of the device that said g snperheating' element, together With the uozzle, may oe easily removed from the rcmainder J'f the device and when so removed said 'supcrheating element an'd said nozzle may be readily separated from each other.

A further object is toprovidc means for regulating andI cleaning thevaperture of the nozzle of the device in such a manner that said aperture will not bc enlarged.

A further object,l is to obtain an economically made dcvice;i\'liich will have a good' appearance, be durable, not liable to get` out of order and easily attached to or installed in what is known as the hollow wire system olE gasolene lighting.
